What is the difference between Хх(); Xx;

Хх(); generates an error if the class does not have a default constructor, and Xx; gives.
no difference calls the default constructor.
Xx; there is no call to the constructor, Xx( )
Xx(); not declares instance of the class and announces prototype functions
there is no correct answer.

Declare a pointer to an integer:

А. int *fun_int = NULL;

B. int fun_int = NULL;

С.char*fun_char=NULL;

D.char fun_char=NULL;

E.char_char=NULL;

Now let’s dereference the pointer:

A.*fun_int=12;

B. .fun_int=12;

C. &fun_int=12;

D. /fun_int=12;

E. fun_int=12;

What is the output?

int main() { int n = 310; funcOne(n); cout << “n = “ << n << endl; return 0; } void funcOne(int n) { n = 240; }

A.240;

B.310;

C.550;

D.70;

E.74400

What is the output?

int main() { int n = 310; funcOne(n); funcTwo(&n); cout << “n = “ << n << endl; return 0; } void funcOne(int n) { n = 240; } void funcTwo(int *n) { n = 120; }

A.120;

B.240;

C.310;

D.70;

E.550;

Now that the pointer is declared, let’s set it to point to something: int a = 5;

A.*fun_int=&a;

B.*fun_int=*a;

C.fun_int=*a;

D.fun_int=&a;

E.fun_int=**a;

int main() { int n = 10; funcOne(n); funcTwo(&n); cout << “n = “ << n << endl; return 0; } void funcOne(int n) { n = 40; } void funcTwo(int *n) { n = 20; }

A.10;

B.40;

C.20;

E.55;

int main() { int n = 31; funcOne(n); funcTwo(&n); cout << “n = “ << n << endl; return 0; } void funcOne(int n) { n = 24; } void funcTwo(int *n) { n = 12; }

A.31;

B.24;

C.12;

D.55;

E.36;

Now that the pointer is declared, let’s set it to point to something: int a = 9;

A.*fun_int=&a;

B.*fun_int=*a;

C.fun_int=*a;

D.fun_int=&a;

Now that the pointer is declared, let’s set it to point to something: int a = 55;

A.*fun_int=&a;

B.*fun_int=*a;

C.fun_int=*a;

D.fun_int=&a;
